The effect of temperature on the rate of a reaction was studied and the following data obtained:k (s-1)T (°C)1.91×10-452.25×10-473.07×10-4113.58×10-4134.84×10-4177.49×10-4231.06×10-3281.22×10-330It is known that the variation of the rate constant k with the absolute temperature T is described by the Arrhenius equation: k = A exp [( −Ea )/(RT)]where Ea is the activation energy, R is the universal gas constant and A is the pre-exponential factor (units of the rate constant). Taking the natural logarithm of both sides affords: ln k = ln A − Ea RT For a plot of y = ln k versus x = 1/T, calculate the slope of the best straight line using linear regression.
